Directivity - Antenna-Theory.com Directivity is a fundamental antenna parameter. It is a measure of how 'directional' an antenna's radiation pattern is. An antenna that radiates equally in all directions would have effectively zero directionality, and the directivity of this type of antenna would be 1 (or 0 dB). Printed Wide-Slot Antenna Design with Bandwidth and Gain ... This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. An I-shaped microstrip line is used to ... Gain Enhancement of a Wide Slot Antenna Using a Second ...

Chapter 8 Slot Antennas - eetrend.com SLOT ANTENNAS Tapered slot antennas (TSAs) were first introduced in the late 1950s. It was then that Eberle et al9 produced a waveguide-fed, flared slot antenna for use in aircraft skins where conventional antennas could not be easily integrated. Gibson10 then developed the strip-line-fed, exponentially tapered slot antenna, which he called the ...
